I am having a slight issue with the 'Line sync' effect in TV Simulator. When the lines go out of sync little gaps are created at the sides of the screen. The issue is that the gaps are rather bright and this is distracting as the video is rather dark. It is as though there is a white screen behind the main picture which shows through at the sides. Is there a way to change this to black? That way it would not be as noticeable. Thanks!
